Trencor Wheel Trenchers
Trencor offers two state-of-the-art industry mechanical drive wheel trenchers for utility and pipeline work.
Trencor wheel trenchers feature extended length crawlers, fully enclosed and oil bath lubricated chain final drives, multiple drilled digging rims, and in most cases, double segmented rims. Direct mounted hydraulic hoist cylinders for optimum digging performance are standard on all models.
Contractors have found that in certain conditions, one wheel trencher can replace an entire fleet of backhoes.

Considered mainly as a trenching specialist, UNAC has used its know-how for activities as varied and complex as the forest or railroad industries. UNAC trenchers are available on caterpillar tracks or tyres. Their power transmission is entirely hydrostatic, which makes it possible to :
- Obtain continuous speed transition.
- Ensure hydrostatic braking due to circuit reversibility.
- Limit efforts : a pressure-limiting valve placed on the hydrostatic circuit eliminates overloads
- Obtain device flexibility : the heat engine is positioned in such a way as to contribute to the machine's equilibrium.
UNAC platform trucks are multi-purpose. Changing from one tool to another (saw, chain or ploughshare) can be done in approximately one hour. This means the same platform truck can be available on all types of sites. Thanks to the turntable levelling system and the hudraulic offset, the tool remains vertical at all times. The power mechanizations available are CATERPILLAR 180CV - 275CV and DEUTZ 450CV - 550CV. The standard tools are the saw (0.50 m to 1.40 m deep by 60 mm to 550 mm wide) and the chain (0.50 m to 2.50 m deep by 150 mm to 600 mm wide).

The improvements made as a result of the experience of the 300P series 1 to 3 have made it possible for UNAC research department to design and produce the UNAC series 4 300P, equipped with a new generation 300hp CATERPILLAR diesel engine. The UNAC 300P carrier is versatile. Changing from one tool to another - saw, chain or vibrating ploughshare - can be done in an average time of one hour. This makes it possible for the same carrier to be availbale for all types of worksite. Thanks to the tilt corrector and hydraulic offset, the tool remains permanently vertical.
The 300P also exists in a 500hp version. On the same basis as the 300P carrier, UNAC has developed the 300C carrier, on caterpillar tracks. It has been studied for work in all conditions, and is equipped with a chain and vibrating ploughshare.
